Acanthus eminens, commonly known as the Blue Acanthus, produces large clusters of striking deep blue flowers that bloom from March to July atop large, decorative holly-like leaves. 
Reaching heights of 1 to 2 meters when fully grown, the Acanthus eminens is perfect for creating a dramatic focal point in your landscape. While it can thrive in a variety of conditions, this hardy species prefers a relatively frost-free winter for optimal flowering, withstanding temperatures to 0°C.
This plant flourishes in both half-shade and full sun environments, making it versatile for various gardening settings.
